I wouldn't use anything that's got salt in it... as Stefan said. If you checkered is pregnant, the good news is that checkereds are one of the easiest garters to get feeding, and they often will take pinky parts unscented without any scenting needed. As babies, for first meals I always offer cut up worms. Then then next meal I offer cut up fish. Then I start mixing the two and mixing in pinky parts. Eventually they will eat anything you throw at them!!!
